tadpole.c assigned cpu_pwr_save based on the current configuration.
The rest of the tadpole.c file was only used if cpu_pwr_save was
dereferenced.
But this variable was never dereferenced - and I went back to a 2.6.12
kernel to check (from June 2005) - and not even then was it used.
Drop this code as it has not been in use for ~10 years.

====================
sparc32: introduce asm-generic
Inspired by Michal Simek <monstr@monstr.eu> this patch-set
introduces asm-generic/io.h for sparc32.
As the diff-stat tells this was a nice code-reduction.
The changes are done on top of the previous sent sparse warning cleanup.
But I do not expect any difficult conflicts if applied alone.
leon_pci + pcic are touched because they had local
and identical implementations of functiones that are
static inline in asm-generic/io.h
leon_pci_grpci1 + leon_pci_grpci2 are touched becuse they
used a sparc spacific implmentation of swab32.
They have just been changed to use the global variant.
I also looked at sparc64 - but there were to many
sparc64 assembler implementations of the io
functons - and the generic io.h did not support this mix.
The last patch kills a few defines in io.h for sbus.
I assume they were introduced before the functions
were all shifted over to __iomem style pointers.
The same could be done for sparc64 - but then
there were even more of the same so I left
this for another time.
The patch-set has been build tested only.
My attempts to test this using qemu have failed as
the qemu version I have errors out.
And my fedora box are mssing some libs to build
qemu from source :-(

====================
sparse warning fixes in arch/sparc/
The following patch-set address a lot of sparse warnings
in the sparc32 specific parts of arch/sparc/.
A few sparc64 bits are touched too when code are shared.
Within arch/sparc/mm/ only two warnings remains.
These are related to the return value of of_ioremap() which is __iomem.
Within arch/sparc/kernel/ only three files now produces sparse warnings:
sys_sparc_32.c
time_32.c
auxio_32.c
The fixes was not obvious so the warnings was left for now.
When looking at tadpole.c I was left with the impression that most
of the code was actually unused - but for now I added a "TODO".
This is made on top of 3.15-rc2.
This set replaces the two sets sent the last days.
V2:
- Do not add extern in front of prototypes.
- Tidy up a few changelongs
There are still sparse warnings left that are easy to address.
But this fixes the majority.

loading a module and enabling function tracing at the same time.
He uncovered a race where the module when loaded will convert the
calls to mcount into nops, and expects the module's text to be RW.
But when function tracing is enabled, it will convert all kernel
text (core and module) from RO to RW to convert the nops to calls
to ftrace to record the function. After the convertion, it will
convert all the text back from RW to RO.
The issue is, it will also convert the module's text that is loading.
If it converts it to RO before ftrace does its conversion, it will
cause ftrace to fail and require a reboot to fix it again.
This patch moves the ftrace module update that converts calls to mcount
into nops to be done when the module state is still MODULE_STATE_UNFORMED.
This will ignore the module when the text is being converted from
RW back to RO.

ftrace/module: Hardcode ftrace_module_init() call into load_module()
This branch contains a pair of important bug fixes for the DT code:
- Fix some incorrect binding property names before they enter common usage
- Fix bug where some platform devices will be unable to get their
interrupt number when they depend on an interrupt controller that is
not available at device creation time. This is a problem causing
mainline to fail on a number of ARM platforms.
